Key Specifications

Core Advantages

1. Genuine Yuchai 4D Series Power Core Original Yuchai four‑cylinder diesel engine with proven mature design. Direct‑injection combustion optimizes fuel consumption, maintains stable output under variable‑load conditions, suitable for long‑term standby operation.
2. STC Brushed Self‑Excitation Alternator Classic STC brushed alternator with AVR automatic voltage adjustment. It keeps steady output voltage during load changes. Simple brush‑type structure, low spare‑part cost and convenient on‑site repair, well‑suited for workshops and construction‑site environments with IP22 protection level.
3. 24V DC Electric Start & Water‑Cooled Circulation System 24V DC electric start supports fast one‑click startup. Standard water‑cooled circulation stabilizes operating temperature and prevents overheating during continuous running. Mechanical governor has simple structure and low failure rate.
4. Cost‑Effective Open‑Frame Unit, User‑Friendly Maintenance Open‑style layout exposes all key components. Operators can easily complete routine maintenance such as filter replacement and daily inspection without complex disassembly. Spare parts are widely available globally.
5. Reliable Three‑Phase Power Output For General‑Purpose Applications Three‑phase 400V/230V output at power factor 0.8 lag. Ideal for factory standby power, small commercial buildings, temporary construction‑site power and emergency power supply.
